Throw on the Costa Del Mar Permit Polarized Sunglasses, jump in your boat, and head out to find your record-breaker. The polarized Costa 580 lenses resist scratches and enhance clarity without feeling heavy, while the stainless-steel hinges scoff at saltwater spray and keep the glasses on your face when you're setting your lines. Three beveled slots on each side of the frame keep the Permit shades from fogging up when you're pulling so you can see the trophy come over the stern.
